General Improvements
- Registration Mark Detection: Now includes an alternative machine learning/computer vision (ML/CV) registration mark detection method to aid with automatic target identification and ROI placement. This new detection method is available for the following analyses: Random/Dead Leaves, eSFR ISO 12233:2017, eSFR ISO 12233:2023, Star Chart, 36-Patch Dynamic Range, Contrast Resolution, ISO 14524, and ISO 15739.
- Improved Handling of DNG files: Added ability to read non-standard bit depth DNG files using direct read option, and Incorporated Adobe DNG SDK into Libraw DNG read option for improved processing according to DNG specification. There is a new dropdown option for the DNG Read method selection in the Options II window, to allow the choice between the original Libraw processing and the new Adobe SDK processing.
- Checkerboard: Now includes a High-distortion option for checkerboard detection, providing improved detection robustness for highly distorted images.
- Rescharts and Color/Tone: Now includes the ability to hide the text overlaid on select plots as an option under the Display dropdown, located at the top of Rescharts and Color/Tone Interactive windows.
Image Information Metrics — from slanted edges
- SNRI and Edge SNRi (Independent Observer Signal-to-Noise Ratios). Measures of the detectability of objects and edges.
- Matched filter design Procedure for designing electronic filters that optimize object and edge detection metrics, SNRi and Edge SNRi.
- Slanted edge SFR interpolated binning method for reducing spurious high-frequency signals from SFR curves. Reduces sawtooth artifacts in motion blur analysis and improves the reliability of MTF10 measurements, but not recommended for general use because it lowpass-filters the SFR.
Refer to this documentation, for instructions on using the new options for information capacity calculations, and more information on the new measurements.
Stray Light (Flare)
- Now includes support for ITU-R BT.709-6, ITU-R BT.2020-2, and MATLAB luminance calculations.
- Now includes the number of saturated pixels per analysis frame.
- Now includes a maximum measurable stray light calculation.
Main Window
- Now includes the ability to annotate images with Custom Metadata.
- Now includes improved General Settings search with highlighting.
Known Issues
This is a Beta version of the software, major issues are listed below:
- Crash occurs when using Registration Mark Detection on a Star Chart
- eSFRiso charts ROI not auto detected if “machine vision autodetect” selected on SFRreg settings
